1. integral from 0 to pi of (4 sin theta -3 cos theta) d theta
I started like this...4 integral from 0 to pi of sin theta d theta -3 integral from 0 to pi cos theta d theta...I got stuck here
what do you mean you "got stuck"? do you know the antiderivatives of sine and cosine ? do you know how to use the fundamental theorem of calculus?
2. How do I calculate this math?
3/4 (8^4/3) - 3/4 (1^4/3) =?
1 to any power is 1.
3. How do I solve this integral?
integral of cos^3 x dx
straight up integration of the first integral ... use substitution for the second , let
